NOTICE
It is recommended that adequate surge protection be used
in order to protect products from voltage changes in your
application.
Grounding
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
• Never remove ground wire from plug. Connect to
grounded outlet protected by Class A GFCI.
Pump: grounded through electrical cord.
Fluid lines: use only electrically conductive lines.
Fluid supply container: follow local code.
NOTICE
In order to prevent over pumping at low back pressure (less
than 50 PSI) install an inline check valve on the outlet line.
Flush Before Using Equipment
The equipment was tested with water. To avoid contaminating your fluid with water, flush the equipm en t with a
compatible solvent before using the equipm en t. See

Plumbing Requirements for Stainless Steel / Plastic Fluid Sections
The Mongoose pump uses carefully matched components to achieve a predictable metering output. This
predictability can only be maintained if all fitting sizes
remain unaltered.
All connections should be double checked to insure
against leakage. If hazardous chemicals are being
pumped, use shielding around outlet fluid lines. NOTES:
• There is an approximate 2.5 psi capability lost for
every 1 foot of vertical rise of the outlet fluid line to
the injection point.
• Do not attempt to reduce tubing size; this may
reduce performance of unit.
Stainless Steel Fluid Section Models
Inlet and outlet valves are both 1/4 in. NPT fittings.
NOTE: Apply PTFE tape to threads on NPT fittings.
Plastic Fluid Section Models
Inlet and outlet valves use 3/8 in. or 1/4 in. tubing connectors, and 3/8 in. or 1/4 in. tubing. See F
IG. 1.
NOTE: The prime/bleed valve on the plastic fluid section
includes a 1/16 in. clear poly tubing. This tubing is to be
used only with the prime/bleed valve and is not intended
for pressurized use. Do not use with the inlet and outlet
valves.
Tighten connectors no more than a 1/4 turn after the
connection feels snug. Hand tighten only. Do not overtighten.
NOTE: Do not apply PTFE tape to threads.

Three-Function Valve Injection Assembly
(Plastic Fluid Section only; Optional)
The optional three-function valve injection assembly
provides three functions in one injection valve asse mbly.
• Anti-siphon - which allows metering of liquids into
the inlet side of a circulating pump. It provides protection against an accidental application of suction
pressure at the fluid injection point. A PTFE coated
diaphragm provides a positive anti-siphon action.
• Back pressure - which permits metering into atmospheric discharge (such as an open container) without overpumping.
• Line check - which permits removal of outlet tubing
without release of system fluid.

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as splashing fluid, follow the
Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or servicing the
equipment.
NOTE: Always discharge fluid into an approved container or location.
1. Turn SPEED knob (H) to off and disconnect power
cord (B).
2. Shut off the inlet and outlet lines using shutoff
valves (C).
3. Slowly crack the fitting connected to the outlet check
valve to relieve downstream fluid pressure.
4. Run the pump until the dispensed fluid is predominately flushing fluid.
5. Follow the Pressure Relief Procedure.
Prime the Pump
1. Connect power (B) to the pump.
2. Set the STROKE % knob (J) to 100%. (See F
on page 10.)
3. Set the SPEED knob (H) to maximum cycles per
second.
While pump is operating, if fluid begins moving, no further priming is required.
If fluid is not moving, open prime/bleed valve (4 or 104)
approximately one turn until fluid begi ns to move. When
the inlet fluid line (D) fills, close prime/bleed valve (4 or
104).
IG. 5
Flush the Equipment
To avoid fire and explosion, always ground e quipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest possible pressure.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted par ts.
1. Follow the Pressure Relief Procedure.
2. Connect inlet fluid line (D) to the supply source of
the flushing fluid.
3. Connect outlet fluid line (E) to a waste container.
NOTICE
Do not overtighten prime/bleed valve. Damage may occur.

Adjust Feed Rate
The Mongoose pump allows for the exact setting of the
pump’s SPEED knob (H) on the pump’s control panel.
IG. 5.
See F
Adjust Stroke Length
The stroke length can be adjusted on the Mongoose
pump. This is a mechanical adjustment made using
STROKE % knob (J) on the control panel.
NOTICE
To avoid damage to the pump, this adjustment
should only be made while the pump is running at a
high-stroking rate.
Calculate Output
A pump’s output per minute can be determined by dividing the maximum rated gallons per day by 1440 (minutes per day).
For example, a 30 gallons per day (gpd) pump at a maximum stroke length and speed setting of 125 cycles per
minute (cpm) will pump 0.000167 gallons per stroke
(gps).
30 gpd ÷ 1440 min/day = 0.0208 gpm ÷ 125 spm =
0.000167 gal/stroke
FIG. 5: Mongoose Control Panel
NOTE: Standard cycles per minute settings available
are: 1, 2, 3, 4, 5, 6, 7, 8, 10, and increase by 5 thereafter
up to the maximum of 125.
With this value and the pump’s speed setting (cycles pe r
minute) you can calculate your pump’s output at it’s
rated pressure.
A 30 gpd pump set at 50 cycles per minute:
50 cpm x .000167 gps x 1440 min/day = 12.02 gpd
Reducing the stroke length will reduce the pump’s output again. If the example pump above had it’s str ok e
length reduced to 50% the 12.02 gallons per day ou tput
is reduced to 6.01. (Example: 12.02 gpd x 0.50 = 6.01
gpd).
A higher product viscosity will reduce the output. Pressures lower than the pump’s rating can increase the output.

Insufficient fluid Stroke adjustment set too low Check operation of STROKE %
Air trapped in inlet line Straighten inlet line to eliminate high
spots.
Worn or contaminated check valves Inspect check valves in fluid end for
cleanliness.
Excessive lift Verify the appropriate lift for the liquid
being pumped. Maximum suction lift
is 5 ft. with water or liquids of similar
specific gravity; though less with
heavier liquids, such as acids. Mount
the pump in a lower position relative
to the chemical container.
Suction fittings not properly tightened Check fittings. Overtightening may
cause restriction. Conversely, if any
leakage occurs, the pump will suck
air and fail to prime.
Split or pinch in inlet tube Inspect inlet tube through its full
length to assure there are no splits at
the connections or other restrictions.
Move objects or equipment which
impinges upon the inlet tube, or
reroute as required to assure a
smooth transition from foot valve to
